STEAMER, LAWN, ANDINVALID CHAIR.

SPECIFICATION forming part of Letters Patent No.329,941, dated November 10, 1885.

Application lcd November 17. 1884. Serial No.148.179.

T a/ZZ whom, it may concern.-

Y Beit known that I, DANA PARKs,of Boston, county of Suffolk,and Commonweath of Massachusetts, a citizen of the United States, re-

siding at said Boston, have invented a new and useful Improvement in Self-Leveling Steamer, Lawn, and Invalid Chairs, of which the following is a specification.

Before my invention steamer-chairs have ro been usually made to fold simply, and were not capable Ofantomatic adjustment. By my improvement the weight and movement of the body of the person occupying the chair operates to adjust the position of the chair to suit that part of the body requiring rest.

In the drawings, Figure l is a perspective view of my chair. Fig. 2 is a side elevation of the chair folded. Fig. 3 is aside elevation of foot-rest.' Fig. 4. is a section of front leg,

2o showing slot and pin. Fig. 5 is a section of arm, eye, and pivot. Fig. 6 is a reduced perspective View of part of the chair, showing it constructed without the frame-legs I.

A is the seat-frame; B, the back-frame; C,

the arms; D, foot-rest; c, arm, eye, and pivot. E are the frame-legs hinged at e. F F are the hangers pivoted at the apex of the frame E. c is the slot in the arm with its channels. G is the rod attached to the ends of the arms to 3o keep back and arms in place. H is the lock at the lower end of the slot in the front hanger to keep theseat in place and prevent the sinking` of the inner end of the seat. I is the opening or closing frame-leg having a pin traversing in a slot in the front leg, used in folding or opening the frame.

I prefer, however, to make the chair more compact, to omit the opening and closing frame-leg I with its pin, and also the slot in 4o the front leg, as the chair can be supported, opened, and closed equally well Without them.

I make my chair with the seat,back,foot,and arms independent in their motion of the frame. The chair is supported by two hangers, F F,

on each side, pivoted to the apex of the frame E. The front hanger is slotted to allow folding and opening. The back hanger, F,is vertical, and serves to support,together with the front (No model.)

hanger, the weight of the body, the front hanger also acting as a guide in folding or 5o opening. Slots extending the length of the arms inside c, in which a pin in the frame of the back B travels, allows adjustment of the back at any angle with the seat desired. Channels in the arms-slots serve by receiving the 5 5 said pin to fasten the back at the desired position. The said slots also allow that part of the chairto be folded or opened. Vhen folded, the chair may be strapped to a trunk as aparcel of baggage. A foot-rest, D, slides in or out under the seat, and a wheel-guide inserted in the side of the seat-frame serves to prevent friction against the arm I. 'Ihe back and seat are hinged together, so that they may be placed at any angle relative to each other to 6 5 afford desired ease and support to the body and back, and also aid in folding and opening. The frame E is hinged at the top or apex e', and rods extending across the frame strengthen and support it. 7c

If any person is seated in the chair or reclining at full length, as upon a bed, and is desirous of changing his position,by the simplest movement of the body the chair automatically assumes the desired position without the aid of any gearing or complicated mechanism, doing away with the labor lattending the use of ordinary steamer, invalid, or reclining chairs.

The hangers of the seat and body of the 8o chair are made and attached to the frame separately, but operating together and move simultaneously with the arms, also attached to the frame E, by a pin passing through an eye inserted into the apex of the stationary frame 8 5 E. A rod is attached to the ends of the arms to keep the back and arms in place. Alock,

H, at the lower end of the slot of the front hanger, is used to keep the seat in place and to prevent the sinking of the inner end of the 9o chair.

A headed bolt with a screw-threaded end passes through the apex of the frame E on either side of the chair, the threaded end passing through a curved slotted piece of metal attached to the arm and frame, and a cranklever, also threaded attached, to said threaded` end of the bolt, serves by turning to tighten and fasten the chair at any desired position.

Having described my invention, what I 5 claim, and desire to secure by Letters Patent,

1. In a steamer, lawn, or invalid chair, the

combination of the hangers attached as described with their locks, the armspivoted, vo slotted and channeled, the hinged seat and back, the adjustable sliding foot-rest With the hinged frame capable of being folded and
